Describe the bug

When several Field provisionActivity.agent are present in ProvisionActivity field, separators displayed are commas (,). This is not correct regarding ISBD/RDA display. Separators used should be semicolons (;)
example :

"provisionActivity": [
{
"_text": [
{
"language": "default",
"value": "[Paris] : EHESS, Gallimard, Seuil, [2021]"
}
To Reproduce

See example

Expected behavior

use semicolons instead of commas as in the example:

"provisionActivity": [
{
"_text": [
{
"language": "default",
"value": "[Paris] : EHESS ; Gallimard ; Seuil, [2021]"
}
